US Gamers
This is a fairly new forum/flash game site owned and developed by 2p2ers (not me, I'm just a shill) that just launched a money system for their arcade. Each game costs 1 USG$ to play, and a monthly jackpot is awarded to the top three scores along with an overall Leaderboard jackpot. Everyone is given 5 USG$ just for signing up, and 10 USG$ for referrals. After that you can earn them by posting in the forum, winning a jackpot, or buying them directly from the USG bank, which uses PayPal. Also, be sure to check out the
Forum Arcade sticky for payouts and other info. Thanks.
